Decorations =)

Okay Blogger Friends!  I'm in the process of planning Emma's 6th Birthday party.  I cannot believe she is going to be 6 years old next month.  Time goes by so fast.  =(  So before I start crying about this, let me get to the point! =)   So my question for all of you is where do you purchase your birthday decorations?  Our theme for her party is going to be a "Princess Tea Party".  I'm looking for decorations that are unique, original and fun.  I've looked on Etsy and found some cute things, but where else are some good places to find some cute decorations?  I'm hoping to go with muted colors, like pinks, purples, greens, blues and yellows.  I'm hoping to make it really cute =)  I'm anxious to hear where everyone purchases their decorations =)
